Engine
The C9 engine, matched with the torque divider and field proven power shift transmission,
provides years of dependable service.
Cylinder Block. Engine durability
begins with its foundation – the engine
block. The serpentine design of the C9
block provides maximum strength in
a reduced weight design. It is a singlepiece, deep-skirted design providing a
solid base for the durability you require
in today’s D6R II.
Cylinder Head. The C9 cylinder head is
designed for maximum breathing, which
helps ensure excellent fuel efficiency.
This one-piece, stress-relieved,
gray-iron casting has four valves per
cylinder. Robust intake and exhaust
valves aid airflow and provide excellent
reliability and fuel efficiency.
Pistons. The two-piece articulated
piston design consists of a forged-steel
crown for maximum strength and a
cast aluminum skirt to reduce weight.
A large piston pin holds the crown,
skirt and connecting rod together.
The aluminum skirt runs cooler than
conventional pistons, allowing a closer
fit to the cylinder liner and providing
longer life. The steel crown handles
the higher internal pressures of
today’s engines.
C9 Engine. The Caterpillar C9 engine
meets worldwide emissions regulations
for the Environmental Protection
Agency (EPA), the European Union
(EU) and the Japan Ministry of
Construction (JMOC).
•
Wastegated turbocharger
for improved response.
•
Extended oil change intervals.
Cylinder Liners. Mid-supported
wet cylinder liners provide excellent
durability and rebuildability.
4
Advanced Fuel System. The C9
features an electronically controlled,
hydraulically-actuated, direct injection
fuel system that provides improved
fuel economy and reduced emissions.
Crankshaft. The crankshaft is a steel
forging with induction-hardened journals
and fillets. The wide center and end
main journals and bearings are designed
to maintain maximum oil film thickness
for excellent lubrication and for
cooling the bearings. The result is
long life-to-overhaul.
Advanced Modular Cooling System (AMOCS)
AMOCS utilizes an exclusive two pass cooling system and increased cooling surface area
to provide significantly more cooling efficiency than conventional systems.
Two Pass Cooling System. Using a two
pass system, the AMOCS radiator
provides a more efficient heat exchange.
The coolant is routed from a sectioned
bottom tank up the front side, over the
top of the core and down the engine
side of the core to the bottom tank.
This flow pattern allows the coolant
to pass through the radiator twice for
better cooling.
Modular Design. The cooling elements
are individual core modules connected
to a sectioned bottom tank. There is no
top tank to remove.
•
Standard nine steel fins per 2.54 cm
(1 in), or an optional 6 steel fins per
2.54 cm (1 in).
•
Brass tube construction within each
core for improved reliability.
Air-to-Air Aftercooler. The D6R II
features air-to-air aftercooling.
Dedicated air-to-air aftercooler circuit
provides cooler inlet air temperatures,
which improves performance and
reduces engine emissions.
Serviceability. Modular core design
permits removal of a single core
without removing the entire radiator,
which reduces repair costs and downtime.
AMOCS eliminates the top tank,
side channels and one sealing surface,
making it more reliable and easier to
service. It features a site gauge for
quick service checks.
Protection From Leaks. To reduce the
potential for coolant leaks, brass tubes
are welded to a large, thick header,
improving strength of the tube-to-header
joint. In conditions where abrasive
materials can be airborne, use the
attachment sand blast grid to prevent
core damage.
Sand Blast Grid. In an application where
airborne debris is prevalent, radiator
core protection is a concern. To extend
radiator life in harsh applications, a sand
blast grid is available as an option to
deflect the damaging debris the engine
fan propels at the radiator.
5
Drive Train
Get maximum power to the ground with the efficiency and reliability you expect from
Caterpillar machines.
Transmission. The D6R II planetary
power shift transmission features three
speeds forward and three speeds reverse
and utilizes large diameter, high-capacity,
oil-cooled clutches. To maximize the
life of the transmission, the planetary
design distributes loads and stresses
over multiple gears.
Torque Divider. A single stage torque
converter sends 70% of engine torque
through a converter and 30% through a
direct drive shaft for greater driveline
efficiency and higher torque
multiplication to get heavy loads
moving. The torque divider provides
improved efficiency and broader range
of performance in second gear
applications.
6
Key Benefits of a Torque Divider.
The D6R II torque divider provides:
•
High reliability.
•
Low dynamic torque.
•
Optimum combination of operator
efficiency and driveline reliability.
•
Components are designed to absorb
full engine power.
•
Controlled throttle shifting regulates
engine speed during high energy
directional shifts for smoother, more
comfortable operation and longer
component life.
•
Electronic clutch pressure control
permits fast speed and direction
changes.
•
Modular transmission and bevel
gear slide into rear case for servicing
ease, even with ripper installed.
•
Oil-to-water cooler for maximum
cooling capacity.
•
Forced oil flow lubricates and cools
clutch packs to provide maximum
clutch life.
Operating Efficiency and Driveline
Reliability. The D6R II torque divider
attains the best combination of
operating efficiency and driveline
reliability. It reduces dozing shock
loads to the transmission and final
drives by acting as a hydrodynamic
component between the engine and
transmission.
Finger Tip Control. The D6R II with
Finger Tip Control features low effort
finger tip levers for steering and touch
shift buttons for upshift and downshift.
The steering clutches and brakes are
fade resistant and adjustment free.
Multi-disk, oil-cooled steering
clutches are hydraulically applied and
electronically controlled. Brakes are
applied by springs and hydraulically
released for safe, reliable braking
performance.
Differential Steering. A D6R II equipped
with differential steering maintains
power to both tracks while turning.
The tractor turns when one track speeds
up and the other slows down an equal
amount. The operator can steer and
control the transmission simultaneously
which can reduce cycle times in some
applications. The differential steering
tiller bar has touch shift buttons for
upshifts and downshifts. The tiller bar
itself is easily rotated forward or reverse
to change the respective tractor direction.
The tiller bar is moved forward to steer
the tractor to the left and pulled back
to go right. Low tiller bar efforts assure
operator comfort during long shifts.
Large blade loads can be maneuvered
around buildings, bridge abutments,
trees, or other obstacles. Steering
modulation is also optimized for precise
control in these applications. Greater
load capacity, power and speed control
are possible in soft underfoot conditions
and on steep slopes because both tracks
are powered during turns.
Auto-Shift/Auto-Kickdown. Auto-shift
allows the operator to pre-select a
forward and reverse gear for easy,
efficient directional changes. Auto-shift
settings include first forward to second
reverse, second forward to second
reverse and second forward to first
reverse. Auto-kickdown allows
the transmission to automatically
downshift when significant load
increases are detected.
Elevated Final Drive. Isolates final
drives from ground and work tool
induced impact loads for extended
power train life.
Thick, Large Diameter Plates and
Clutch Disks. Provides higher torque
capacity and increased service life.
Load Compensating Shifting.
Automatically adjusts the clutch
engagement timing according to load
factor, resulting in improved tractor
performance and operator comfort
during speed changes. Load compensating
shifting reduces the amount of energy
dissipated through the clutches to help
extend transmission component life.
